Intranuclear cascading mechanism one of the important non-linear effects in high energy nucleusnucleus collisions is investigated. The data on multiplicity (ns) and pseudorapidity (η) distributions of shower particles produced by32S and16O at 200A GeV,16O at 60A GeV,28Si at 14.5A GeV and He at ≈140A GeV are presented and compared with the string model VENUS, which takes into account the cascade interactions of secondary particles. The effect of the intranuclear collisions on the distributions of <η> versus <ns> is discussed for all the beams.

Multiplicity and angular distributions of shower, grey, and black particles produced in the interactions of S32 at 200A GeV, O16 at 200 and 60A GeV, and He4 at ∼140A GeV in emulsion are compared with the predictions of a Monte Carlo code which takes into account the internuclear cascading. The correlations between the various parameters belonging to the same or to the different kinds of particles are discussed. The data on shower and grey particles from all the beams are well described by the code. However, the black prong data show a significant departure from this model.
